Glee is an American musical dramady television series that airs on Fox. It focuses on a high school show choir, and is pretty much the most amazing singing-dancing show ever (well, besides FAME perhaps).
Here is a list of characters and the cast members whop play them, and why you should give them a follow.
Finn's girlfriend and head of the Cheerios and celibacy club, Quinn joins the glee club from the second episode because the head of her Cheerios squad, Sue Sylvester, wants a spy inside the club. her character, as well as her tweets, are stereotypically blond and ditzy.
Example: "Wait, what's the difference between Puerto Rico and Mexico? I know one likes plantains"
Sue Sylvester is head coach of the cheerleading squad or "Cheerios", and the Glee Club's "arch-nemesis". Sue is pure evil and doesn't hide it. Sue will do whatever it takes to win. If that means she has to prostitute herself or take advantage of a 16-year-old boy, she'll do it. It's all about power and winning.
Example: "Health insurance is for the weak. I perform all my own medical procedures"
Rachel is an only child, overly ambitious and assertive, with dreams of making it to Broadway. She has two fathers, an interracial same-sex couple. Rachel has a crush on Finn, and the two share a kiss, although he tells her to forget it happened and goes back to his girlfriend, Quinn.
Example: "My gay dads took me to Glamor Shots at the mall and we found the photos to be SUB-PAR. I tried to tell them I NEVER wear cowboy hats!"
Cory Monteith plays Finn Hudson, star quarterback of the school's football team who risks alienation by his friends to join the Glee Club. His tweets are pretty balanced between, personal and GLEE-related.
Example: "Very excited for you all to see my bad dancing tonight! : D lol"
Lea Michele plays Rachel Berry, the talented star of the glee club who is bullied by the Cheerios and football players. Her tweets aren't really about GLEE. They are more about her personal life, which I don't find that interesting but maybe you will.
Example: "On my way to New York City to do David Letterman tomorrow! So excited to do the show and be back in the city!"
